Download or read book Photon-Assisted Resonant Tunneling Through a GaAs/AlGaAs Multiple Quantum Well Structure written by Bjorn Jonsson and published by . This book was released on 1992 with total page 3 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of bandgap engineering techniques to tailor the perpendicular transport characteristics of layered semiconductor structures has resulted in a variety of new phenomena and devices concepts . In particular the coherent interaction of electron waves reflected at interfaces gives rise to resonant tunneling effects which filter electrons of certain energy through the structure. A structure specifically designed for electron energy filtering is the variably spaced superlattice energy filter (VSSEF) in which the quantized states in adjacent quantum wells become aligned under appropriate bias conditions.

Should always be trusted for their word. [From" Dittamondo", by Fazio degli UbertiJ Heterojunction interfaces, the interfaces between different semiconducting materi als, have been extensively explored for over a quarter of a century. The justifica tion for this effort is clear - these interfaces could become the building blocks of lllany novel solid-state devices. Other interfaces involving semiconductors are al ready widely used in technology, These are, for example, metal-semiconductor and insulator-semiconductor junctions and hOll1ojunctions. In comparison, the present applications of heterojunction int. erfaces are limited, but they could potentially becOlne lnuch lllore ext. ensive in the neal' future. The path towards the widespread use of heterojunctions is obstructed by several obstacles

Book Synopsis Resonant Tunneling Through GaAs Quantum Well with Embedded InAs Quantum Dots by : E. E. Vdovin
Download or read book Resonant Tunneling Through GaAs Quantum Well with Embedded InAs Quantum Dots written by E. E. Vdovin and published by . This book was released on 1999 with total page 3 pages. Available in PDF, EPUB and Kindle. Book excerpt: This article investigated the electron resonant tunneling through the GaAs quantum wells with embedded InAs quantum dots. It was found that the localised perturbation generated by the inAs quantum dots strongly influences the wave functions of the sub-band states in the quantum wells. The "inverted bistability" of the third resonance was observed for the samples with quantum dots. The shape of the resonances on the I-V curves under inverted bistability differs from that previously observed adding to the collection of the butterfly-like resonances on the double barrier structures.

Book Synopsis Intersubband Transitions in Quantum Wells by : Emmanuel Rosencher
Download or read book Intersubband Transitions in Quantum Wells written by Emmanuel Rosencher and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the lectures delivered at the NATO Advanced Research Workshop on the "Intersubband Transistions in Quantum Wells" held in Cargese, France, between the t 9 h and the 14th of September 1991. The urge for this Workshop was justified by the impressive growth of work dealing with this subject during the last two or three years. Indeed, thanks to recent progresses of epitaxial growth techniques, such as Molecular Beam Epitaxy, it is now possible to realize semiconductor layers ( e.g. GaAs) with thicknesses controlled within one atomic layer, sandwiched between insulating layers (e.g. AlGaAs). When the semiconducting layer is very thin, i.e. less than 15 nm, the energy of the carriers corresponding to their motion perpendicular to these layers is quantized, forming subbands of allowed energies. Because of the low effective masses in these semiconducting materials, the oscillator strengths corresponding to intersubband transitions are extremely large and quantum optical effects become giant in the 5 - 20 ~ range: photoionization, optical nonlinearities, ... Moreover, a great theoretical surprise is that - thanks to the robustness of the effective mass theory - these quantum wells are a real life materialization of our old text book one-dimensional quantum well ideal. Complex physical phenomena may then be investigated on a simple model system.
